I am in NYC but can travel for it...
I am upstate ny near port jervis every other weekend so can stop anywhere between nyc and port jerivs. Will also be willing to take one via shipping...

the rest of the fish are smaller but there are quite a few of them... All together I think I have about 15 smaller fish in there.

I feel like I had too many deaths since my tank started. What testing kits should I get? (I mean - what should I test for?)

Oh... No lead weights in my tank.

I have a eheim 2213... I might buy that API test kit to see what is going on...

Tank info: 18x18x18" cube with temp of about 76-79. Ph is about 6.4
I do not have a test kit for the rest.

The tank has been running for about 3 months now. I have other fish in the tank from very early on.

What is "lead weights" on the leaves mean?

I bought 5 and they were ranging from 2.5-4"... The day after they arrived and were acclimated - I found the first floating around dead. The next day another died, and the next another. Today I pulled the last two who were dead is well... I have other fish in the tank, some were also newly acquired ...
